gelii

Gelii is a Latin word form most commonly encountered as either the genitive singular or the nominative plural of the Roman nomen Gellius. As a second-declension noun, Gellius yields Gelii to indicate possession ("of Gellius") or to refer collectively to members of the Gellius family. The form appears in classical texts, epigraphic inscriptions, medieval manuscripts, and modern scholarly citations where Latin grammatical forms are preserved.

In classical studies, Gelii may be found in references to authors or historical figures with the nomen Gellius; the best-known bearer is Aulus Gellius, author of the Noctes Atticae (Attic Nights). Epigraphists and historians encounter Gelii in the rendering of Roman names and legal or dedicatory formulas. The form is also visible in editions and commentaries that retain Latin case endings for names.

Outside strict grammatical usage, Gelii can appear in compounded or Latinized modern contexts—for example as part of bibliographic references that follow Latin conventions or, less commonly, in taxonomic or onomastic formations derived from classical names. Because it is fundamentally a grammatical form rather than a separate lexical entry, Gelii is primarily of interest within linguistic, historical, and philological study.
